I been six days there and I took small room. I arrived in the night of January 1st and Parawit give me all explanation not only how to enter in the Loft but how to go there from the airport. Normally several hotels ask to pay the day more when you arrive in the night but not Parawit.
I stay in the small room 4 days and I asked to change for a more large one and he give the good one on the 4th floor and he adjust the price for the last 2 days. I had problem with the aircon and he give another room and also he refund the price extra to the large room. Was not necessary because at this this time of the year we dont need really aircon for all night but he insist to refund. Parawit is a great Host and the staff are very welcoming also.
Suanplu place is a good place to discover if you know Bangkok. They have street foods on the street of the hotel, good restaurant, massage place and not far for night life of Bangkok for 10 min of taxi/tuk tuk/Mototaxi.
Finally a good hotel with cheap price in the middle of city without be in the Bangkok jungle ;)
